A still further object of the invention is to provide a storm windowwhich can be compactly folded when not in use and stored in acompartment formed in the wall and beneath the sill.

With these and other objects in View, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in

' which Figure 1 is an outside view of the window.
